AI Goblin Possum Coding 2027-2028 Calendar

OpenAI tried to stop their models from talking about goblins. They failed spectacularly. This calendar celebrates the glorious moment when GPT-5.5 went full "goblin mode," forcing OpenAI to add a rule—repeated four times—that explicitly forbids mentioning "goblins, gremlins, raccoons, trolls, ogres, pigeons, or other animals or creatures" unless absolutely relevant to the user's query . The company later traced the infestation to ChatGPT's "Nerdy" personality, which incentivised mythical creature references . The result? An AI that couldn't stop describing everything in "goblin mode," giving "goblin versions" of answers, and obsessing over "perf gremlins" . The meme exploded across X, with users sharing screenshots of GPT-5.5's bizarre creature fixations. Sam Altman himself joined in, posting a meme asking for "extra goblins" in GPT-6 . This calendar is for the AI enthusiasts, the coders who've wrestled with an agentic AI going off the rails, and anyone who finds deep irony in a company trying to code away its own goblin problem. Each month pairs a creature—goblin, gremlin, possum, racoon, pigeon—with a coding joke or AI fail. It's a full 2-year planner of mischief. Organised by months, with all creatures allowed. Order now before OpenAI bans them again.
